Andrew watched Jack with pleading eyes but knew they'd be ignored, and he was proven right when Jack proceeded to the next stage. He took in a slight breath at Jack behind him, the arm around his waist, but then did so again as Jack commanded the broom to rise, only this time it was a little tense noise of anxiety.
He wanted to refuse and tell Jack that he couldn't, but it was no worse than sitting on a bench or something and he was already a laughing stock as he was; he didn't want Jack to be anymore ashamed of him than he imagined Jack to already be, and so he gingerly, timidly, took his feet off the ground, his knuckles white around the broom and the tension felt in his body as he tensed up.
